Review
The gastrointestinal tract is an unusual site for teratomas to occur. Only 4 prior cases of teratomas involving the cecum have appeared in the English literature, the latest published in 1977. To the best of our knowledge, this is the first report to describe fine-needle aspiration cytologic findings in addition to histologic features of a mature cystic teratoma involving the gastrointestinal tract. A 30-year-old man presented with right upper quadrant abdominal pain and a palpable abdominal mass. Radiographic studies identified a mass lesion inferior to the liver and in close association with the ascending colon. Fine-needle aspiration biopsy showed scant keratinous material and anucleated squamous cells. Right colectomy revealed a cystic mass in the wall of the cecum that contained keratinous material and was lined by stratified granular squamous epithelium with sebaceous glands. Clinical and pathologic features with review of the literature are presented, and the differential diagnosis for pericolic cystic masses is discussed in detail.

Review
The ovary shows an innate potential for markedly variable histogenesis, including squamous differentiation. Although not uncommon, squamous differentiation in ovarian lesions can be present in several diagnostic contexts, both benign and malignant. We present a review of the literature pertaining to squamous lesions of the ovary. In particular, we summarize the relevant clinical features, workup, gross findings and histopathologic features, differential diagnosis, treatment, and prognostic features of both the common and rare squamous entities found in the ovary.

We describe the unusual case of a female patient with a history of two mature teratomas non-correlated in terms of location and occurrence. A 12-year-old girl presented at our consultation as a result of a growing tumor in the hypogastric region, with no further clinical signs. She had undergone surgery neonatally due to a mature cystic sacrococcygeal teratoma, which was fully removed. No clinical sequelae were noted and no additional treatment was required over a 10-year follow-up. Radiological examination showed a large 20 × 12 × 18 cm cystic mass extending from the pelvic region to the lower hemiabdomen, associated with two similar small formations adjacent to the right ovary. Tumor markers were negative, and a laparoscopic right salpingoophorectomy was carried out, with an excellent postoperative progression. Pathological examination revealed it was, again, a mature cystic teratoma. The genetic study ruled out causation in this respect.

Review
A 26-year-old woman presented with acute onset of right-sided pelvic pain and had a medical history significant for migraine headaches and polycystic ovarian disease. Ultrasonography demonstrated bilateral ovarian tumors, and the patient underwent laparoscopic removal of bilateral cystic teratomas. A literature review focused on similar presentations of teratomas revealed isolated cases of migraines and polycystic ovarian disease associated with teratomas and an increased risk for ovarian torsion. Our patient experienced complete resolution of her acute abdominal pain, as well as her long-standing headaches and hormonal symptoms, after removal of the teratomas.

Eye (London, England) Feb 2023To evaluate the clinical features of developmental cysts of the orbit.
PURPOSE
To evaluate the clinical features of developmental cysts of the orbit.
PATIENTS AND METHODS
Retrospective study of patients who had excision of cysts between 1992 and 2020.
RESULTS
Three hundred and 58 patients (189 male; 53%) with orbital developmental cysts were identified, all being unilateral. Age at surgery varied from birth to 77 years (mean 17, median 18 years) and the average symptom duration was 5 years (median 18 months; range 1 day-50 years). The commonest presenting features were a peribulbar lump or upper lid swelling, followed by proptosis, pain, diplopia and reduced vision. Most patients (82%) had a palpable mass, with epidermoids, sebaceous dermoids and keratinised dermoids commonly affecting the superotemporal quadrant, and conjunctiva-containing cysts usually being biased to a medial location. Cysts were lined by keratinised epithelium with dermal structures (224/358; 63%), non-keratinised epithelium with dermal structures (69/358; 19%), epidermis without identifiable dermal structures (19/358 'epidermoids'; 5%), conjunctiva (12/358; 3%), respiratory epithelium (4/358; 1%), or mixed dermal and conjunctival epithelia (30/358 'dermo-conjunctival' cysts; 8%). Overall, two-thirds (242/358; 66%) had histological evidence of chronic intramural inflammation, and a half of cysts showed granuloma formation (178/358 cysts). Chronic inflammation was less common with conjunctival cysts (54%, 7/12 patients) and none showed granuloma formation.
CONCLUSION
Developmental cysts of the orbit vary from the relatively common dermoid cysts to the extremely rare respiratory epithelial-lined cysts. Respiratory cysts, being deeper, may present late in life and cysts containing conjunctival epithelium tend to be less inflamed and typically favour the superonasal quadrant.

Review
Dermoid cysts account for 10-20% of ovarian germ cell tumors. Malignant transformation within ovarian dermoid cyst has been reported in 1-2 per cent of the cases. The treatment remains controversial. In women of childbearing age and in the first stages of the disease unilateral annexectomy without adjuvant therapy is recommended. In menopausal women extensive surgery is sometimes performed, no matter what stage of the disease the person is experiencing. We report the case of a menopausal patient with malignant transformation within ovarian dermoid cyst who underwent surgery. She had a favorable outcome.
